  13 * @shortname: a short discription for the DAC, seen by userspace tools.

  15 * This struct contains the configuration of the hardware connection to the
  16 * external DAC. The DAC needs a master clock and a I2S audio stream. It also
  17 * provides a name which is used to identify it in userspace tools.
